SPECIFICATION forming part of Letters Patent No. 548,609, dated October 22, 1895.

Serial No. 555,301. (No model.)

To all whom t may concern: V

Be it known that I, HENRY R. FRIsBIn, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and. useful Improvements in Oil-Feed Injectors, of which the following is aspecitication.

My invention relates to oil-injectors, the irnprovements of which will be more fully described in the following speciiication, and such features as 1 believe to be new and novel particularly set forth in the claims to follow.

To enable others to fully understand my invention reference is had to the accompanying drawing, in which is shown a side elevation and sectional view of the injector attached to abroken sectional view of the steam-pipe leading from the boiler to the engine-cylinder. Its construction and operation are as follows:

1 represents the steam-feed pipe. 2 is a screw-plug attached to a threaded holein such pipe and projecting therein, to which plug is attached the injector-body 3 by means of the threaded union-nut 5.

5 is a valvestem controlled by the handle 6, and Whose threaded portion 5a engages with a threaded portion of the body 3. The pointed end 5b of such stem is adapted to cover and uncover the valve-seat 7 for the admission of steam and also for the oil-feed along the needle-point or Wire S, presently to be more fully described.

9 is a glass connected by the screw-caps 10 10 to the injector-body 3 and the feed-plug connection 11, the latter having the oil-chamber 11' therein and the hollow threaded end 11", by which it is connected with the oil-reservoir 12.

13 is an oil-feed stem whose threaded portion 13 engages With a threaded hole in the feed-plug connection 11. Said stem has the tapered valve-point 13b to engage with theof surface which is presented to the atmosphere by means of such corrugations, condenses steam much faster than if such outer surface Were plain or unbroken.

16 is a tube Whose upper end 161L is screwed into the lower portion-ad of the condenser, and which upper end projects about two-thirds through the same, while the lower end of such tube extends nearly to the bottom of the oilreservoir 12. This tube operates as an overtioW for the condensation which takes place,

in the condenser 15, carrying the water therefrom to the bottom of the oil-reservoir. The oil is admitted to the oil-reservoir by removing the plug 17 in the upper part, such oil floating on the surface of the Water, the height of the latter being regulated to about the dotted line e by means of the dripcock 18, which is set so that the pointed end 18 will be raised from the seat suiticient to let the Water pass into the chamber fof thescreW-plug 19, thence through the channels g and h of the cock 1S.

2O is a steam oil-heating pipe Whose free ends open into the interior of the injectorbody 3, the two branches passing through the solid portion 15a of the condenser and into the oil-reservoir. One or more holes, as t' j, are provided in such pipe to let out the Water which may be lodged therein from condensation of the steam. The object of this pipe is to carry the live steam into the oil so as to thin it. The pipe 16 serves in a measure this same purpose; but it is not suflicient where crude or heavy oil is used.

The operation of the device is as follows: Steam is admitted from the pipe 1, thence through the valve-seat 7 into the condenser 15, and also into the tube 16 and pipe 2O for thinning the oil. The condensation taking place in such condenser soon fills the same to the height of the tube 16, which tube, as before mentioned, carries the overflow to the bottom of the oil-reservoir. When, therefore, the feedestem 13 is opened, circulation is instantly started, the oil from the reservoir pass ing through the port 11E into the chamber 11a, and from thence it passes off the needle or Wire point 14 in drops, as shown, or in a solid stream, if desired, the iioW being regulated by the opening of such feed-stem, the oil drops passing through the Water in the glass tube 9 and through the valve 7, and from ICO thence they 'will drop oft from the needle or wire point 8 down into the steam-pipe l, as Shown.

The injector above described presents many features that are both new' and novel. The corrugated condenser affords a much better facility for condensation than the constructions usually employed and the facility with which the oil is heated by the direct steam, so that the crudest and heaviest oils can be used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The herein described improvement in oil injectors, comprisingiu combination, the body 3 having the Valve stem 5 therein, a drip Wire at its free end, an oil reservoir having a drip plug at the bottom thereof; a corrugated condenser depending from the injector body and connected With the oil reservoir; a central overow tube in such reservoir and condenser, as shown, plug connection ll and oil-feed stein 13, said stem having a taper face thereon to engage with a taper seat in such plug connection; a feed Wireon the inner free end of said stem 13; a sight glass connecting said plug connection With the injector body, for the purpose set forth.

2. The improvement in oil injectors, of the character described, comprising in combination, injector body 3; means for attaching said body to the steam pipe; a corrugated condenser and oil reservoir depending from said injector body, as shown, means for producing the necessary circulation for feeding the oil from the reservoir; a central overiow tube extending Within said reservoir and condenser; an auxiliary oil heating pipe passing through the condenser into the reservoir, as shown, the free ends of said pipe projecting into the injector body, as set forth.

Signed at Newark, in the county of Essex and State of New Jersey, this 14th day of June, A. D. 1895.
